Suppose that you have an unlimited supply of copper 2 chloride to react with iron. How many moles if copper would be produced by 34.0 grams of iron with the copper 2 chloride solution
This is a regular stoichiometry probolem.
Write and balance the equation.
CuCl2 + Fe ==> FeCl2 + Cu
mols Fe = grams/molar mass = ?
Use the coefficients (they are 1:1) to convert mols Fe to mols Cu. Since the ratio is 1:1 then mols Fe = mols Cu.
Now convert mols Cu to g Cu.
g Cu = mols Cu x atomic mass Cu.
